ROLAND L. HAY,.OF LANCASTER, OHIO, ASSIGNOR TO FRIG'K & LINDSAY COMPANY, OF PITTSBURGH, PENNSYLVANIA,' A CORPORATION OF PENNSYLVANIA.

PUMP VALVE;

Specification of Letters Patent.

Application filed July 9, 1919. Serial No. 309,679.

T 0 all whom it may concern Be it known that I, ROLAND L. HAY, a citizen of the United States, and resident of Lancaster, in the county of F'airfield and State of Ohio, have invented a new and useful Improvement in Pump Valves; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to working valves used in connection with pumping of oilwells.

These valves as constructed heretofore have consisted of a barrel, a head screwed into said barrel, and a crown screwed onto the upper end of said head, the cups, rings and lock-nuts being interposed between the bottom head of said barrel and said head.

The object of my invention is to reduce the number of parts heretofore used to make up these valves and so simplify the construc tion as well as the cost of production.

To these ends my invention comprises the novel features hereinafter set forth and claimed.

In the accompanying drawing Fig. 1 is a vertical elevation of my improved valve; Fig. 2 is a vertical section; and Fig. 3 is a 'crosssection,on the line 33, Fig. 1.

In the drawing the numeral 2 designates the barrel which is of uniform diameter with the bottom-head 3 formed integral therewith, said head consisting of the cage-like structure having the openings 4 for the admission of the fluid to the interior of the barrel.

Surrounding the barrelabove the head 3 are the cups 5 and rings 6 of the ordinary construction which are tightened up and held fast between said head and the top ring 7 7 locked in place by the lock-nut 8.

The crown 9 is threaded interiorly as at 10 and is screwed onto the threaded portion 11 of the barrel, said crown having the shoulder 12 which fits down on the'flange 13013 the valve-seat 1% and secures said valve in place. The ball 15 normally rests uponthe valve-seat 14:. The lock-nut 16 is employed to prevent the unscrewing of the crown 9 whenthe pump is in use. I v

The crown 9 is hexagonal in cross-section for convenience in turning as indicated in Fig; 3 and has the openings 17 to permitthe escape of the fluid into the well.

By my invention I provide a valve bodycomposed of'only two parts, namely the barrel and the crown, thereby reducing the number of parts toa minimum and obtaining a stronger constructions The rigid construction'and simplicity of the valve gives it very important advantages over other valves composed of a greater number of parts, and anything which will reduce the" number of connected parts in a valve of this Patented Aug. 15 192.2.

character which is used at such great depth insures more effective pumping.

Whatl claim is:

A working or pumping valve for oil-well pumps, comprising a barrel having a bottom-headintegral therewith, a crown secured directly to the upper end of said barrel, cups and rings on said barrel, interposed between said head and a lock-nut engaging the uppermost of said rings, and a lock-nut on said barrel engaging the lower end of said crown. I

In testimony whereof, I, the said ROLAN L. HAY, have hereunto set my hand.
